☆ 简介

本文只考虑Win10中Python便携化。如果读者没有这种需求,或者无法理解这种需求, 直接忽略本文。

Win10提供WSL,安装Win版Python的必要性降低,但不是所有环境都装有WSL。

原始需求是Python解释器及各种第三方库"All In One"式地出现在一个目录下,该目 录可以随意复制、移动到其他目录、其他PC而不影响使用。此处所谓不影响使用,并 不包括PATH环境变量之类的设置,那些属于小白式便捷,不在考虑范畴。

这事并不需要很多奇技淫巧,最简方式是在虚拟机中安装Python,安装相关模块,复 制Python安装目录到别处,卸载虚拟机中的安装版Python;跟大多数绿色软件的搞法 一样,没有技术含量。

本文展示Python便携化的更多细节,但未给出采用建议,随缘自取。

☆ 官方便携版Python

官方已经提供便携版Python:

https://www.python.org/downloads/ https://www.python.org/downloads/release/python-390/ https://www.python.org/ftp/python/3.9.0/python-3.9.0-embed-amd64.zip

把python-3.9.0-embed-amd64.zip展开到任意目录,比如"X:\Python39\",执行其中 的python.exe即可。便携版没有include*.h、libs*.lib、Doc*.chm。

高阶用户可自行建立到.py的文件关联,不建也无所谓,每次用python.exe显式执行 .py即可。按需修改PATH环境变量,我就不修改。

X:\Python39> python.exe -c "import sys;print(sys.path)" ['X:\Python39\python39.zip', 'X:\Python39']

缺省情况下sys.path中只有python39.zip和当前目录。

对比一下安装版Python:

https://www.python.org/ftp/python/3.9.0/python-3.9.0-amd64.exe

C:\Python39> python.exe -c "import sys;print(sys.path)" ['', 'C:\Python39\python39.zip', 'C:\Python39\DLLs', 'C:\Python39\lib', 'C:\Python39', 'C:\Python39\lib\site-packages']

尽管安装版Python的sys.path中出现python39.zip,但安装版没有显式提供它,它已 经被解压展开了。如果需要"Portable IDAPython",只能从便携版Python中析取 python39.zip。

尽管官方提供便携版Python,但事实上安装版Python一样可以随意复制、移动到其他 目录、其他PC而不影响使用,对高阶用户尤其如此。本质上Python解释执行所需要的 东西都在安装目录下了,安装版Python所做全局设置仅仅增加不必要的小白式便捷, 比如修改PATH环境变量、提供pip.exe、增加.py文件关联、增加定位Python安装目录 的注册表项等等,没有这些也不真正影响使用。官方便携版Python意义有限。

"pip install"的真正动作是"python -m pip install",后者要求pip模块就位,检查 这个位置:

\Lib\site-packages\pip\

安装版Python提供pip模块,可以选装,其版本是20.2.3,用如下命令升级:

$ python.exe -m pip install --upgrade pip

$ python.exe -m pip --version pip 20.2.4 from C:\Python39\lib\site-packages\pip (python 3.9)

☆ 便携版pip模块

1) 给便携版Python安装便携版pip模块

编辑python39._pth,原内容是:


python39.zip .

Uncomment to run site.main() automatically

import site


改成:


python39.zip . Lib/site-packages

Uncomment to run site.main() automatically

import site

从如下链接下载get-pip.py放入Python解压目录:

https://pip.pypa.io/en/stable/installing/ https://bootstrap.pypa.io/get-pip.py

执行get-pip.py安装pip模块:

$ python.exe get-pip.py Collecting pip Downloading pip-20.2.4-py2.py3-none-any.whl (1.5 MB) Collecting setuptools Downloading setuptools-50.3.2-py3-none-any.whl (785 kB) Collecting wheel Downloading wheel-0.35.1-py2.py3-none-any.whl (33 kB) Installing collected packages: pip, setuptools, wheel WARNING: The scripts pip.exe, pip3.9.exe and pip3.exe are installed in 'X:\Python39\Scripts' which is not on PATH. Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location. WARNING: The scripts easy_install-3.9.exe and easy_install.exe are installed in 'X:\Python39\Scripts' which is not on PATH. Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location. WARNING: The script wheel.exe is installed in 'X:\Python39\Scripts' which is not on PATH. Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location. Successfully installed pip setuptools wheel

几个告警忽悠你修改PATH环境变量,不用理。

确认pip模块就位:

$ dir Lib\site-packages\pip\

$ python.exe -m pip --version pip 20.2.4 from X:\Python39\Lib\site-packages\pip (python 3.9)

以后这样升级pip模块

python.exe -m pip install --upgrade pip

2) 用便携版pip模块安装其他模块

没有修改PATH环境变量,不能"pip install ...",只能"python -m pip install"。

$ python.exe -m pip install hexdump

$ dir Lib\site-packages\hexdump.py

查看已安装的模块:

$ python.exe -m pip list

Package Version


hexdump 3.3 pip 20.2.4 setuptools 50.3.2 wheel 0.35.1

测试新安装的hexdump模块:

import hexdump hexdump.hexdump(b'123456')

$ python.exe -c "import hexdump;hexdump.hexdump(b'123456')"

3) 解析python39._pth

参看


The initialization of the sys.path module search path https://docs.python.org/3.11/library/sys_path_init.html#pth-files

Finding modules https://docs.python.org/3.9/using/windows.html#finding-modules


python39._pth内容如下


python39.zip . Lib/site-packages

Uncomment to run site.main() automatically

import site

python39._pth前部每一行都是一条路径,"import site"让这些路径进入sys.path:

['X:\Python39\python39.zip', 'X:\Python39', 'X:\Python39\Lib\site-packages']

这就是"import site"意义所在。如果不让"import site"生效,可以复制

X:\Python39\Lib\site-packages\pip\

X:\Python39\

或将pip目录添加到python39.zip中,这样才能使用pip模块。显然hexdump模块也可 照此办理,但吃撑了才用这种复制目录的方案,修改python39._pth更简捷优雅。

python39._pth的用途可能同PYTHONPATH环境变量及下述注册表项:


Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\SOFTWARE\Python\PythonCore\3.9\PythonPath] @="C:\Python39\Lib\;C:\Python39\DLLs\"


reg.exe add "HKCU\SOFTWARE\Python\PythonCore\3.9\PythonPath" /v "" /t REG_SZ /d "C:\Python39\Lib\;C:\Python39\DLLs\" reg.exe query "HKCU\SOFTWARE\Python\PythonCore\3.9\PythonPath" /v "" reg.exe delete "HKCU\SOFTWARE\Python\PythonCore\3.9\PythonPath" /v "" /f reg.exe delete "HKCU\SOFTWARE\Python\PythonCore\3.9\PythonPath" /f reg.exe delete "HKCU\SOFTWARE\Python" /f

☆ PyCrypto

"pip install"有时需要编译源码,这事在Windows上不太理想,比如安装pycrypto模 块就会遭遇。

1) Visual Studio 2019 社区版

https://visualstudio.microsoft.com/zh-hans/downloads/ https://visualstudio.microsoft.com/zh-hans/thank-you-downloading-visual-studio/?sku=Community&rel=16 https://download.visualstudio.microsoft.com/download/pr/2f4a234d-6e7c-4049-8248-6d9ac0d05c96/05e09aacb072da5204d4d9d3b3c61c9069b729e38da34965ebb254eec00347b9/vs_Community.exe

社区版免费下载、使用,不需要序列号什么的。

为了编译pycrypto模块,并"不"需要这些组件:


How to install Python support in Visual Studio on Windows https://docs.microsoft.com/en-us/visualstudio/python/installing-python-support-in-visual-studio

Python development Python native development tools


就正常的C/C++组件即可。

2) 给安装版Python安装pycrypto模块

先给安装版Python安装pycrypto模块,降低一下难度,别骚包地直接给便携版Python 安装pycrypto模块。

有一个可选前置步骤,不做也无所谓:

$ python.exe -m pip install wheel

如果没有wheel模块,会用传统setup.py安装方式。

$ "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsall.bat" amd64

$ python.exe -m pip install pycrypto

报错

C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.28.29333\bin\HostX86\x64\cl.exe /c /nologo /Ox /W3 /GL /DNDEBUG /MD -Isrc/ -Isrc/inc-msvc/ -IC:\Python39\include -IC:\Python39\include -IC:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.28.29333\ATLMFC\include -IC:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.28.29333\include -IC:\Program Files (x86)\Windows Kits\NETFXSDK\4.8\include\um -IC:\Program Files (x86)\Windows Kits\10\include\10.0.18362.0\ucrt -IC:\Program Files (x86)\Windows Kits\10\include\10.0.18362.0\shared -IC:\Program Files (x86)\Windows Kits\10\include\10.0.18362.0\um -IC:\Program Files (x86)\Windows Kits\10\include\10.0.18362.0\winrt -IC:\Program Files (x86)\Windows Kits\10\include\10.0.18362.0\cppwinrt -IC:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.28.29333\ATLMFC\include -IC:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.28.29333\include -IC:\Program Files (x86)\Windows Kits\NETFXSDK\4.8\include\um -IC:\Program Files (x86)\Windows Kits\10\include\10.0.18362.0\ucrt -IC:\Program Files (x86)\Windows Kits\10\include\10.0.18362.0\shared -IC:\Program Files (x86)\Windows Kits\10\include\10.0.18362.0\um -IC:\Program Files (x86)\Windows Kits\10\include\10.0.18362.0\winrt -IC:\Program Files (x86)\Windows Kits\10\include\10.0.18362.0\cppwinrt /Tcsrc/winrand.c /Fobuild\temp.win-amd64-3.9\Release\src/winrand.obj winrand.c C:\Program Files (x86)\Windows Kits\10\include\10.0.18362.0\ucrt\inttypes.h(27): error C2061: syntax error: identifier 'intmax_t'

去找找哪个.h包含"intmax_t"。一般用UltraEdit搜,这次试试Win10的高级搜索

Advanced options File contents Other properties Name

在搜索框输入"intmax_t name:*.h",命中:

C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.28.29333\include\stdint.h

参看:

CL environment variables https://docs.microsoft.com/en-us/cpp/build/reference/cl-environment-variables?view=msvc-160

cl.exe认CL、CL_环境变量,%CL%被加在cl.exe参数的最前面,%_CL%被加在cl.exe 参数的最后面。

$ cl.exe /help

/FI name forced include file

$ echo %VCToolsInstallDir% C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.28.29333\

$ dir "%VCToolsInstallDir%include\stdint.h"

$ set CL=/FI"%VCToolsInstallDir%include\stdint.h"

这相当于"#include "。重新编译安装pycrypto模块:

$ python.exe -m pip install pycrypto

没有其他幺蛾子,顺利完成。

$ python.exe -m pip show pycrypto Name: pycrypto Version: 2.6.1 Summary: Cryptographic modules for Python. Home-page: http://www.pycrypto.org/ Author: Dwayne C. Litzenberger Author-email: [email protected] ... Location: c:\python39\lib\site-packages ...

$ dir Lib\site-packages\Crypto\ $ dir Lib\site-packages\pycrypto-2.6.1-py3.9.egg-info

小结一下步骤:

"C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsall.bat" amd64 set CL=/FI"%VCToolsInstallDir%include\stdint.h" python.exe -m pip install pycrypto

注意,编译安装过程用到了:

C:\Python39\include*.h C:\Python39\libs*.lib

3) pycrypto-2.6.1.win-amd64-py3.9.exe

PyCrypto - The Python Cryptography Toolkit https://www.dlitz.net/software/pycrypto/ https://www.dlitz.net/software/pycrypto/doc/ https://www.dlitz.net/software/pycrypto/apidoc/ https://ftp.dlitz.net/pub/dlitz/crypto/pycrypto/ https://ftp.dlitz.net/pub/dlitz/crypto/pycrypto/pycrypto-2.6.1.tar.gz

假设解压缩到

C:\pycrypto-2.6.1\

目录随意,只是示例。

cd /d C:\pycrypto-2.6.1\ set CL=/FI"C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.28.29333\include\stdint.h" C:\Python39\python.exe setup.py build dir /s *.pyd

一切顺利的话,就得到一堆*.pyd,实际是64位的dll。有意思的是,这种编译方式并 不需要事先执行"vcvarsall.bat amd64"设置编译环境,setup.py自己去找编译器, "pip install"时必须手动设置编译环境。

C:\Python39\python.exe setup.py bdist_wininst dir dist\pycrypto-2.6.1.win-amd64-py3.9.exe

得到pycrypto的二进制安装包。不想搞编译环境的,用这个:

https://scz.617.cn/python/pycrypto-2.6.1.win-amd64-py3.9.exe

MD5 b585c59e1a9a5a92fc1eca8d63f0458d SHA256 6ddc4fbc1090045e388b1282720cb141f52801089ec4964d1b89242e8725ef2e

3.1) pycrypto-wininst.log

pycrypto-2.6.1.win-amd64-py3.9.exe安装时会生成:

C:\Python39\pycrypto-wininst.log C:\Python39\Removepycrypto.exe C:\Python39\Lib\site-packages\pycrypto-2.6.1-py3.9.egg-info C:\Python39\Lib\site-packages\Crypto*

.log内容如下:


*** Installation started 2020/11/20 14:57 *** Source: C:\pycrypto-2.6.1.win-amd64-py3.9.exe 999 Root Key: HKEY_CURRENT_USER 020 Reg DB Key: [Software\Microsoft\Windows\CurrentVersion\Uninstall]pycrypto-py3.9 040 Reg DB Value: [Software\Microsoft\Windows\CurrentVersion\Uninstall\pycrypto-py3.9]DisplayName=Python 3.9 pycrypto-2.6.1 040 Reg DB Value: [Software\Microsoft\Windows\CurrentVersion\Uninstall\pycrypto-py3.9]UninstallString="C:\Python39\Removepycrypto.exe" -u "C:\Python39\pycrypto-wininst.log" 200 File Copy: C:\Python39\Lib\site-packages\pycrypto-2.6.1-py3.9.egg-info 100 Made Dir: C:\Python39\Lib\site-packages\Crypto 200 File Copy: C:\Python39\Lib\site-packages\Crypto\pct_warnings.py ...


在"程序和功能"里增加卸载项,实际操作是:

"C:\Python39\Removepycrypto.exe" -u "C:\Python39\pycrypto-wininst.log"

复制如下内容到相应位置即可完成安装:

C:\Python39\Lib\site-packages\pycrypto-2.6.1-py3.9.egg-info C:\Python39\Lib\site-packages\Crypto*

如果不是通过pycrypto-2.6.1.win-amd64-py3.9.exe安装,就没有.egg-info文件, 而是:

C:\Python39\Lib\site-packages\pycrypto-2.6.1.dist-info* C:\Python39\Lib\site-packages\Crypto*

复制如上内容到相应位置同样完成安装。

4) RC4_Test.py


-- coding: cp936 --

import sys, os, binascii from Crypto.Cipher import ARC4

def RC4 ( key, sth ) : return( ARC4.new( key ).encrypt( sth ) )

end of RC4

if 'main' == name : if len( sys.argv ) < 3 : print( 'Usage: %s ' % os.path.basename( sys.argv[0] ) ) else: key = binascii.unhexlify( sys.argv[1] ) sth = binascii.unhexlify( sys.argv[2] ) outdata = RC4( key, sth ) print( binascii.hexlify( outdata ).upper() )

""" C:\Python39\python.exe RC4_Test.py 0B0B0B0B0B0B0B0B0B0B0B0B0B0B0B0B 0A0A0A0A0A0A0A0A b'C05C2982D61530CA'

5) 给便携版Python安装pycrypto模块

这个没有实际意义,写下来仅仅出于完备性考虑。

便携版没有include*.h、libs*.lib,只能从安装版中复制这些目录到便携版目录; 编译pycrypto模块时需要这些目录。假设已经安装Visual Studio 2019 社区版,安 装步骤如下:

set PYTHONHOME=C:\Python39\ "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsall.bat" amd64 set CL=/FI"%VCToolsInstallDir%include\stdint.h" python.exe -m pip install pycrypto

相比前面的安装版,额外设置PYTHONHOME环境变量,否则编译时找不到include*.h。

pycrypto-2.6.1.win-amd64-py3.9.exe不能直接用于便携版Python,因为无法定位 Python目录。需要如下注册表项:


Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\SOFTWARE\Python\PythonCore\3.9\InstallPath] @="C:\Python39\"


reg.exe add "HKCU\SOFTWARE\Python\PythonCore\3.9\InstallPath" /v "" /t REG_SZ /d "C:\Python39\" reg.exe query "HKCU\SOFTWARE\Python\PythonCore\3.9\InstallPath" /v "" reg.exe delete "HKCU\SOFTWARE\Python\PythonCore\3.9\InstallPath" /v "" /f reg.exe delete "HKCU\SOFTWARE\Python\PythonCore\3.9\InstallPath" /f reg.exe delete "HKCU\SOFTWARE\Python" /f

手工添加上述注册表项后,pycrypto-2.6.1.win-amd64-py3.9.exe可以安装到便携版 Python中,然后可以删除上述注册表项。没有实际意义,只是说可以这样干。

☆ PyCryptodome

参看:

https://www.pycryptodome.org/en/latest/src/introduction.html https://github.com/Legrandin/pycryptodome

PyCryptodome用来代替不再维护的PyCrypto。按官方说法,如果完全替换:

pip uninstall pycrypto pip install pycryptodome

此时继续使用"import Crypto"。如果想二者并存:

pip install pycryptodomex

此时后者使用"import Cryptodome"。还是二者并存吧,毕竟很多PoC用前者。

1) 给安装版Python安装pycryptodomex模块

假设已经安装Visual Studio 2019 社区版

$ python.exe -m pip install pycryptodomex --no-binary :all:

这个安装简单,完全没有幺蛾子,不需要手动设置编译环境。

产生目录:

C:\Python39\Lib\site-packages\pycryptodomex-3.9.9-py3.9.egg-info* C:\Python39\Lib\site-packages\Cryptodome*

复制如上内容到相应位置即可完成安装。检验安装效果:

$ python.exe -m Cryptodome.SelfTest

2) RC4_Test_1.py


-- coding: cp936 --

import sys, os, binascii from Cryptodome.Cipher import ARC4

def RC4 ( key, sth ) : return( ARC4.new( key ).encrypt( sth ) )

end of RC4

if 'main' == name : if len( sys.argv ) < 3 : print( 'Usage: %s ' % os.path.basename( sys.argv[0] ) ) else: key = binascii.unhexlify( sys.argv[1] ) sth = binascii.unhexlify( sys.argv[2] ) outdata = RC4( key, sth ) print( binascii.hexlify( outdata ).upper() )

""" C:\Python39\python.exe RC4_Test_1.py 0B0B0B0B0B0B0B0B0B0B0B0B0B0B0B0B 0A0A0A0A0A0A0A0A b'C05C2982D61530CA'

C:\Python39\python.exe RC4_Test_1.py 0B0B0B0B0B0B0B0B0B0B0B0B0B0B0B0B C05C2982D61530CA b'0A0A0A0A0A0A0A0A' """


3) 给便携版Python安装pycryptodomex模块

这个没有实际意义,写下来仅仅出于完备性考虑。

单独下载这个文件到便携版Python目录:

https://github.com/Legrandin/pycryptodome/blob/master/compiler_opt.py

便携版Python的sys.path比较奇特,好像不包含点号(.)对应的当前目录,pip安装时 setup.py找不到同一目录下的compiler_opt.py。

便携版没有include*.h、libs*.lib,只能从安装版中复制这些目录到便携版目录; 编译pycryptodomex模块时需要这些目录。假设已经安装Visual Studio 2019 社区版, 安装步骤如下:

python.exe -m pip install pycryptodomex --no-binary :all:

这次不需要设置PYTHONHOME环境变量,安装结束后可以删除compiler_opt.py。

4) pycryptodome-3.9.9.win-amd64-py3.9.exe

git clone https://github.com/Legrandin/pycryptodome

假设展开到

C:\pycryptodome\

目录随意,只是示例。

不需要事先执行"vcvarsall.bat amd64"设置编译环境,setup.py自己去找编译器。

cd /d C:\pycryptodome\ del .separate_namespace C:\Python39\python.exe setup.py bdist_wininst dir dist\pycryptodome-3.9.9.win-amd64-py3.9.exe

得到pycryptodome的二进制安装包。上面的"C:\Python39\python.exe"对应安装版 Python,但可以是从安装版复制而得的绿色版,并不要求是原始安装版。这次不能用 官方便携版Python,否则最后会失败:

Traceback (most recent call last): File "C:\pycryptodome\setup.py", line 467, in setup( File "C:\Python39\Lib\site-packages\setuptools__init__.py", line 153, in setup return distutils.core.setup(**attrs) File "distutils\core.py", line 134, in setup File "distutils\dist.py", line 483, in parse_command_line File "C:\Python39\Lib\site-packages\setuptools\dist.py", line 903, in _parse_command_opts nargs = _Distribution._parse_command_opts(self, parser, args) File "distutils\dist.py", line 555, in _parse_command_opts distutils.errors.DistutilsClassError: command class must provide 'user_options' attribute (a list of tuples)

不想搞编译环境的,用这个:

https://scz.617.cn/python/pycryptodome-3.9.9.win-amd64-py3.9.exe

MD5 8fd03655b46e208ece6b1b4899cc199c SHA256 0016a53ec355d4f5480a18697218f3cab524f0195a8bbb8e55237418735258b9

这个版本用"import Crypto",不能与pycrypto-2.6.1.win-amd64-py3.9.exe共存, 务必卸载其中一个再安装另一个。

我得吐槽,pycrypto才1MB,pycryptodome有13MB,而常用加密、散列算法在前者中 都有实现,如非绝对必要,就用前者好了。

5) pycryptodomex-3.9.9.win-amd64-py3.9.exe

制做步骤:

cd /d C:\pycryptodome\ copy /y /b NUL .separate_namespace C:\Python39\python.exe setup.py bdist_wininst dir dist\pycryptodomex-3.9.9.win-amd64-py3.9.exe

不想搞编译环境的,用这个:

https://scz.617.cn/python/pycryptodomex-3.9.9.win-amd64-py3.9.exe

MD5 bb92ab13f406b0fbbc41fa27477cd89c SHA256 2907f33b935b85f4b5e373e0482d9733812f03a752cc859354fd85bd7b3fc48e

这个版本用"import Cryptodome",可以与pycrypto-2.6.1.win-amd64-py3.9.exe共 存。

我是怎么知道那条copy命令的呢?因为最开始没有创建.separate_namespace文件, 得到的pycryptodome-3.9.9.win-amd64-py3.9.exe把pycrypto破坏了,然后去翻看 setup.py源码,有这么一段:


use_separate_namespace = os.path.isfile(".separate_namespace")

project_name = "pycryptodome" package_root = "Crypto" other_project = "pycryptodomex" other_root = "Cryptodome"

if use_separate_namespace: project_name, other_project = other_project, project_name package_root, other_root = other_root, package_root


如果setup.py所在目录有.separate_namespace文件,就会生成pycryptodomex,反之 生成pycryptodome,copy命令就是确保出现.separate_namespace文件。

☆ Portable IDA+IDAPython

Q:

IDA已经绿色化,现在不想让IDA去找安装过的Python,事实上也没安装Python,但又 需要用IDAPython。启动IDA时提示:

LoadLibrary(X:\Green\IDA\plugins\idapython3.dll) error: 找不到指定的模块。 X:\Green\IDA\plugins\idapython3.dll: can't load file

启动后底部没有Python命令栏。

下载便携版Python

https://www.python.org/downloads/ https://www.python.org/downloads/release/python-390/ https://www.python.org/ftp/python/3.9.0/python-3.9.0-embed-amd64.zip

从python-3.9.0-embed-amd64.zip中析取如下文件:

python3.dll python39.dll python39.zip python39._pth _ctypes.pyd libffi-7.dll

复制到IDA根目录,比如:

X:\Green\IDA\

一般情况下已经可以使用IDAPython。如果再有问题,用Process Monitor监控 ida64.exe,补齐缺失的组件。从此随意移动IDA根目录到别处使用。

按前述办法简单处理后,在IDA的Python命令栏已经可以执行很多Python代码,但毕 竟Python环境不完善,有可能在后续使用中碰上问题,见招拆招。

比如,在IDA的Python命令栏输入"import socket",提示:

Traceback (most recent call last): File "", line 1, in File "", line 259, in load_module File "socket.py", line 51, in ModuleNotFoundError: No module named '_socket'

此时需要复制如下文件到IDA根目录:

_socket.pyd select.pyd

我是怎么知道的呢?愣试是一种办法,我则是用Process Monitor监控便携版 python.exe,在后者中"import socket",看它加载了哪些文件。

偷懒的话,把python-3.9.0-embed-amd64.zip中所有文件复制到IDA根目录好了,一 堆pyd、dll文件。不过IDAPython编程比较特殊,很可能不需要那些库。

D: scz 2020-11-20

IDAPython可能会去找这些注册表项:


Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\SOFTWARE\Python\PythonCore\3.9\InstallPath] @="C:\Python39\" "ExecutablePath"="C:\Python39\python.exe" "WindowedExecutablePath"="C:\Python39\pythonw.exe"

[HKEY_CURRENT_USER\SOFTWARE\Python\PythonCore\3.9\PythonPath] @="C:\Python39\Lib\;C:\Python39\DLLs\"


找不着时有其他尝试。便携版Python肯定没有这些注册表项,安装版Python有。

Q:

IDA 7.6 SP1已经绿色化。按前述办法将Python相关文件置于IDA相关目录,启动时告 警:

WARNING: Python 3 is not configured (Python3TargetDLL value is not set). Please run idapyswitch to select a Python 3 install.

IDA 7.5系列无此问题。

A: scz 2021-05-01

IDA 7.6相比IDA 7.5在寻找Python解释引擎的套路上有变,后者会尝试当前目录,前 者不会。7.6有个idapyswitch.exe用于处理此事,如欲使用当前目录下的Python引擎, 可以这样:

$ idapyswitch.exe --force-path .\python3.dll

它实际设置注册表项


Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\SOFTWARE\Hex-Rays\IDA] "Python3TargetDLL"=".\python39.dll"


reg.exe delete "HKCU\SOFTWARE\Hex-Rays\IDA" /v "Python3TargetDLL" /f reg.exe add "HKCU\SOFTWARE\Hex-Rays\IDA" /v "Python3TargetDLL" /t REG_SZ /d ".\python39.dll" /f reg.exe query "HKCU\SOFTWARE\Hex-Rays\IDA" /v "Python3TargetDLL"

若不想固定在3.9版,可以这样:

reg.exe add "HKCU\SOFTWARE\Hex-Rays\IDA" /v "Python3TargetDLL" /t REG_SZ /d ".\python3.dll" /f

让python3.dll去找具体的python3x.dll

☆ 后记

搞这些东西,还是Linux省心省力。

除了pycrypto,以前我还编译过Win版pycurl、pylibssh2、python-lzo等,各有各的 坑,当时编译它们是为了制做一些绿色版exe。随着Win10+WSL的普及,这种需求不再 那么强烈,但并不是绝对不再出现。

无论如何,我搞了两个绿色版Python 3.9,装了若干模块,到处复制着用。

本文写得很细,按照操作指导手册的性质来写的,为的是降低照猫画虎的门槛,能 "All In One"式地完成从0到1的跨越,希望本文能帮到那些有此需求的人们。

Happy Hacking!
